DIPPINGr-FORM-CLEANING APPARATUS.

Application filed October 23, 19261 Serial No. 143,680.

This invention relates to apparatus for cleaning dipping forms suchV asused for Y making dipped rubber goods as, for example, finger cots,nipples, gloves, etc.

The general purpose of the invention is tofprovide an improved apparatusfor effectively cleaning dipping forms. In particular the invention hasfor its object the provision of means for feeding form boards carryingrotatable forms along` a path, means for rotating the forms as theboards are moved along the path and means operable against the forms(duringtheir travel and while rotating) progressively from one end tothe other thereof for effectively cleanrlllhe foregoing and otherobjects `are obtained by the construction shown in the accompanyingdrawings and described below.

.It isto be understood that the invention is not limited to the specificform vthereof shown and described.

Of the accompanying drawings,

Figure 1 is a side elevation of a portion of an apparatus illustratingthe invention applied thereto;

Figure 2 is a plan thereof;

Figure 3 is a section on line 3-3 of Figure 1;

Figure 4 is a section on line 4 4 of Figure 1; and

Figure 5 is a section on line 5-5 of Figure 1.

Referring to the drawings, the numeral designates a slide comprising`spaced members 11, 11 along `which form boards 12,12, having two rows ofrotatable forms 13, `13 depending therefrom, may be moved shown) priorto the cleaning apparatus de picted `in the drawings. In order to rotatethe forms 13 as they pass through the cleaning apparatus, plates 20, areprovided on each side of slide 10 and yieldingly urged inwardly bysprings 21, 21 into frictional engagement with rollers 22, 22 secured tothe forms 13.

. The cleaning devices comprise horizontal brushes 23, 23, 24, 24 and25, 25 arranged Vly downwardly from their bottoms to their tops; and ahorizontal brush 27 arranged beneath the path of the forms to brush thetop ends thereof.

For driving of the various brushes, a` motor may be employed which isarranged to drive a shaft 34 having thereon reversely arranged bevelgears 33,33 meshing with bevel gears 32, 32 on shafts 37, 37 so as todrive said shafts in opposite directions. Shafts 37 are in turn geared`to shafts31 at 36, 36 and shafts 31 are arranged to drive brushes 23,24`and 25 by` sprockets 30, 30 driving. chains 29, 29 which are trainedover sprockets 2S, 28 connected to brushes 23, 24 and 25. Bevel gears33011 shafts 37 mesh `with bevel gears 39 to drive brushes 26. A

per) edges by the 'brushes 23, 24 and 25, ad-

jacent each row. The forms are then subjected toa series of brushingactions progressively downwardly from their bottoms (upper portions) totheir tops (lower portions) by brush`es26. Finally the forms aresubjected to a brushing of their top ends (lower ends) by brush 27 andpass from the machine ready for reuse in dipping articles.

It will appear that, due to rotation of the forms, only one brushoperating on one side of each form is required for performing a cleaningoperationen each form and by k arranging the brushes in pairs with theforms traveling between them two rows of forms may be effectivelycleaned at the same time. The machine, accordingly, is adapted foreffective cleaning of `forms in a rapid and economical manner. y y

` Modifications of the invention may be resorted to without departingfrom the spirit thereof or the scope of the appended claims.
